To allwhom it may concern: r Be it known'tha't I, OLIVER HENRY, a citizenof the United States, residing at Ohioago, inthe county of. Cook and State of Illinois, have invented certain new and use- 'ful Improvements in Wrenches, of whichthe following is a specification.

This invention relates pipe wrench, wherein the various adjustments "thereof may be quickly" obtained, whilethe construction is such as to facilitate the gripping of pipes of various shapes.

One object of thisinventionis the projduction of a pipewrench which includes'a movable jawcarried upon the fixed jaw, the.

movable jaw being of an angularconstrue tion, whereby the fixed jaw may/grip an element at the angle of the movable j aw;

jaw for the'receptionof a spring, thesp'ring I ing the v wrench Anotherobject of this inventionflis the production of a pipe wrench wherein a socket is provided in th'ef-s'ideofzthe' fixed eing connectedto the movablejaw and also to the fixed 'jaw,'wher eby the movablejaw will move to a firm engagement withan article inserted between the jawsfthus 'allowto 'be easily operated with one hand. e

' One practical form of construction and assembly of the present invention will be hereinafter described and is illustrated in the drawings, in which:--- I Figure lis a detail perspective :view of the wrench illustrating in dotted lines the manner in which the device is used.

Fig. 2 is a fragmentary elevation of the wrench a portion of the movable jaw being shown in section.

In the preferred embodiment of the press ent invention about to be described, 5 lndicates the fixed jaw which has the tapering shank extending therefrom which constitutes the handle 6. Thus it will be seen that ,the fixed jaw and the handle are integral.

The fixed jaw 5 has a curved inner surface 7 providedwith the gripping teeth 7 it, being noted that the fixed end.

The movable jaw 8' comprises a body 9 having a projection 10 extending at right angles thereto, thus forming a substantially L-shaped structure to provide an angular jaw tapers toward its receiving portion at the inner portion of the movable jaw. The body 9 of the movable jawis also provided with gripping teeth, 11

in general 'to wrenches and has partlcular reference to a sp cim n of cers Patent. Patented Mar. 9,1920.

Application filed Marcn4,1919. Serial asasssf upon its inner surface. The projection 10 is bifurcated as shown at 12, thus providing apair of bearing earsv 13 carried in parallel relation. .The bifurcation 12 is made to provide the slantinginnerwall let to accommopivotal movement of the 5 fixed date the jaw 5. v g V I The fixed j awis inserted between the ears 13'andthebearing pin 15 is'passedthrough the ears 13 and also through-the fixed jaw 5,

thus pivotally mounting the movable jaw upon the fixed jaw.

In order to force the movable j awtoward v i the fixed jaw, the spring16 surroundsthe pin 15 and has fingers '17 extending therefrom. yThe fixed jaw 5is provided with a socket l8'inflone side surface thereof-itbeing madam this socket 18 is open upon one side thereof as at 19 to communicate with one. edge of the-fixed jaw as shown in Fig.

2. One finger 17 of the spring 16 is fixed in engagement with the fixedjaw '5 adjacent. the inner end of the.socket18. Theremain ing finger 17 is fixed byta projection 17" thereon in engagementlwitho-ne of the ears] 13 of the movable jaw. Therefore it will be noted that the tensionofj the" spring; 16 will swingthe movable jaw to the position shown in Fig; 2 atwhi'ch time the end of the fixed jaw will be adjacent the body of the movable jaw. 7 e .1

When-the device is in use, the body of the movable jaw may be placed in engagement with the pipe and then by pulling upon'the body of the movable jaw it is obvious that it' will be swung away from the fixed jaw, thus allowing the pipe tobe moved into the angle of the movable jaw and at this timeby a discontinuation of such pulling upon the movable jaw, it will be noted that the tension of thespring will bring the movable jaw into 'firm engagement w +he pipe and at this time the fixed jaw will also, be engaging the pipe as indicated in Fig. 11-. Thenby pulling upon'the handle 6 asfindicated by the position of the hand in dotted lines in Fig. I

1, the jaws will be urged toward each other and thus the pipe will be more firmly gripped. The teeth will also grip the pipe to hold the wrench from slipping when such a pressure is being applied thereto. Because of the angular construction of the movable jaw, the wrench will grip not only.

round pipes, or round structures, but will possessed of more sides of a fiat nature.

Furthermore because of the an gular construction of the movable jaw, the

I tapered end of'the fixed jaw, articles of va- Qrious. shapes may be easily grippedtherebetween. Also the provision of the socket 7 provides suflicient room for the spring, a1-

though the socketfis formed to allow the spring to easily move as the movable jaw is'being swung although when" the jaws are released the movable jaw jwill'bring an artilcle so engaged'in to position between the fixed law and the movable jaw as will allow the article tolbe easily gripped. v

foregoing description and 'laccom- .panying drawings have reference to what might befconsidered to be the preferred or approved form offmy invention. I desire it to be understood that I inaymake such changes in the construction, combination and arrangement, of parts, materials, dimensions,

combination of a fixed solid jaw having a handle extending therefrom, said fixed jaw having a socket formed in one side thereof, .thesocket having an open side communicating with one edge of the fixed jaw, an enlarged L-sh ap'ed movable jaw having a bifurcated end embracing said fixed jaw, a
